File extension pka is traditionally associated with the PKarc compression utility and used for one of its default compressed archives.
PKarc was released in the mid-1980s in addition to duplicating the compression techniques used in ARC, added an additional algorithm which produced smaller files. Created by Phillip Walter Katz author of popular zip compression.
A .pka file is the standard compressed archive created with PKarc. It is very rare to find such archive nowadays.
It seems that this archive type can only be extracted with PKArc only, but perhaps other tools like 7-zip can help you.
Various archives can be typically repacked to between different formats, including pKA format. However, finding a program that still support this format can be tricky.

The pka file extension is associated with Packet Tracker, a network simulation software developed by Cisco Systems, Inc.
Packet Tracer is the interactive network simulation and learning tool for Cisco CCNA instructors and students. It allows users to create network topologies, configure devices, inject packets, and simulate a network with multiple visual representations.
The pka file contains activity data of a practice session.
*.pka files can be opened in Packet Tracker.
